The USS Thresher (SSN-593) sank with all hands on april 10, 1963. Thresher was undergoing deep-diving exercises off Nantucket.
About fifteen minutes after reaching test depth, the catastrophic failure of a pipe joint in the engineering spaces caused uncontrollable flooding and the boat was lost with all 129 people on board.

"Mosaic of the sail. The conning station is at Arrow (1), upside down with the leading edge to the left in this photograph. The sail planes (2) are completely reversed. Below the sail is a torpedo shutter door (3). An air bottle is at (4) ... . Actuating gear for torpedo shutter door (5)." Quoted text is from the caption released with the original image, which was received by the Naval Photographic Center in December 1966.I was 16 then and joined the boat service 3 years later. My mother said “I knew I shouldn’t have let you watch ‘Silent Service’ and ‘Victory at Sea’ on TV.” She was worried, but I told her it was all Lloyd Bridges fault because in ‘Sea Hunt’ he always survived everything, so I’ll be okay. Mom still didn’t like the idea.
